The packed opening day of CES in Las Vegas saw high definition take centre stage, and big was the theme.

Both Panasonic and Samsung claimed to have the world's largest plasma TVs on their stands. Both are 1080p high definition displays but unfortunately for Samsung, Panasonic's is 103inches compared to Samsung's 102.

These TVs are unrealistic for all but a few people, but we are seeing LCD TV sizes finally begin to rise and compete with mainstream plasmas.

Samsung had an 82inch LED-based LCD TV, which again it claimed as a world's largest, plus LCDs from 15 to 57inches. Two, the 40 and 46inch TVs, boast 1080p resolutions.

And Sony had seven new Bravia LCDs, ranging from 26 to 46inches. Joining Panasonic's 103inch monster will be three large screen LCD TVs this year - at 52, 56 and 61inches. There was no indication of release date though.
